HAY STACKER AND LOADER.

SPECIFICATION forming part of Letters Patent No. 769,673, datedSeptember 6, 1904.

Application filed January 16,1904. Serial No. 189,365. N model.)

To 1077 "12 1/0112.- it ntrty cor/err:

it known that I, TDIOTHY A. \VILLIAns, a citizen of the United States,residing at \Vinigan, in the county of Sullivan and State of Missouri,have invented a new and useful Hay Stacker and Loader, of which thefollowing is a specification.

This invention relates to devices employed in stacking or ricking hayand similar products and materials, and has for its object to simplifyand improve the construction of such devices and increase their powerand capacity, without adding to the expense of their construction orcausing a complication of parts.

The invention consists in certain novel feai i l tures of construction,as hereinafter shown and described, and specified in the claims.

In the drawings illustrative of the invention, in which correspondingparts are de* noted by like designating characters, Figure 1 is aperspective view of the device depressed, or in position to receive itsload. Fig. 2 is a side elevation of the device elevated, or in positionto discharge its load. Figs. 3 and 1 are enlarged detail views of theframework, illustrating more fully the construction of its parts. Fig. 5is a view of the derrick member detached.

The improved device consists of a base member formed of spaced sides orrunners 1O 11, connected at their ends by transverse bars 12 1.3 andsuitably strengthened by diagonal braces 1-1, as shown.

Pivoted at 15 .16 to the runners 10 11 near their forward ends are theside arms 17 and 18 of the fork, which are connected near their rearends by a cross-bar 19 and diagonal braces 20 and have their forwardends scarfed, as at 21 22, and connected by spaced cross-bars 23 and 21,the ends of the latter being extended beyond the side arms, as shown.The tines of the fork are connected to cross-bars 23 21 and aresupported at an angle to the longitudinal plane of the side arms by thescarling of the arms, as will be obvious. By extending the bars 21beyond the side arms l7 l8 provision is made for correspondinglyextending the width of the fork, and to support and strengthen theseextended portions diagonal braces 26 27 are disposed at the sides, asshown. Guard-lingers 28 are pivoted to the tines near their butt-endsand rest normally upon the cross-bar 23 and are supported thereby tolimit their outward movement, to serve as rear supports to the load andprevent its falling from the fork when elevated. The guard-lingers areconnected and supported by a transverse bar 29, as shown.

Pivoted at 30 31 to the runners 10 11 in the rear of the pivots 15 16 ofthe side arms 17 18 are radius-bars 32 33, connected at their upper endsby a cross-bar 34: and having a rod 35 extending transversely throughtheir upper free ends, as-shown.

Pivoted upon the rod 35 outside the bars 33 are yokes 36 37, embracingthe side arms 17 18 and forming loose coupling means between radius-barsand side arms, as will be obvious. Rollers 38 39 are journaled upon therod 35 within the yokes 36 37 and bear upon the lower surfaces of theside arms l7 l8, and thus complete the couplings between radius-bars andthe side arms of the fork.

Pivoted at 40 41 to the ends of the member 12 by straps 12 as is aderrick formed of side bars 1 .5, converging toward their free ends andconnected to a central longitudinal member 16. The member 16 of thederrick is connected by rods 17 as to the free ends of the radius-bars,as shown. Springs -19 are connected between the free ends of the sidearms 17 1S and the radius-bars 33 at intermediate points thereon and areadapted to exert a force upon the side arms to cause them to start ontheir return to normal position, as will be hereinafter explained. Anoperatingcable 51 will be connected to the free end of the member #16 ofthe derrick and is carried over suitable pulleys 52 to secure therequisite power for operating the apparatus.

Any suitable motive power, such as animal or steam, may be employed foractuating the cable 51, and as the means for operating the device formsno part of the present invention it is not shown.

In operating the device the fork is depressed, as shown in Fig. l, withthe derrick inclining ASSN INOR TO AUGUSTUS rearwardly or over the freeor operating end of the fork and with the tines 25 fiat upon the ground,ready to receive the load from therakes or other gathering implements.NVhen the load is in position, power is applied to the cable 51, withthe result of tilting the derrick forwardly and causing the rods 47 48to elevate the fork into a vertical position, as shown in Fig. 2, and todeliver the load to the rick or stack. The loose guard-fingers 28 servean important function in this connection, as they hold the load whilebeing elevated and effectually prevent it from falling backwardly fromthe fork. As the fork and its load is elevated into a vertical positionor slightly beyond the vertical, it might not readily return by gravityto its normal position, and to obviate this the springs 49 50 areprovided, to which a strain is imparted as the fork is elevated, and thereactionary of this force of the springs thus created draws the forkrearwardly until it has moved past the center or until the force ofgravity can become active.

It will thus be obvious that a simply-constructed and efficient deviceis produced by which relatively heavy loads may be elevated and a stackor rick built up by the expenditure of the minimum of force and labor.

It will be noted that by the arrangement shown the pull of the derrickis almost directly vertical when first applied and when the load isheaviest and the force is gradually reduced as the load approaches itshighest point, or where a comparatively small force is required tocomplete the throw of the fork. Consequently the force is automaticallyadapted to the load and the power is decreased relatively as therequired force diminishes. Thus no waste of energy occurs in operatingthe device.

The springs 49 50 will preferably be adjustable to control the tension,as by sections of chains 53 54, interposed between one end and the arms17 18 or the bars 32 33.

The rods 47 48 are preferably detachable from the derrick, as indicatedat 55, so that the latter can be lowered flat upon the frame work whenthe device is to be stored or shipped.

The members of the device may be constructed of any size or strength ofmaterial and will generally be of wood as light as consistent with thestrains to which they will be subjected, andmay be varied inproportionsand modified. in other minor particulars without departingfrom the principle of the invention or sacrificing any of itsadvantages.
